Python Programming:

Hi! I am writing a GUI in Python that inputs the users name, weight, and height and returns their name, bmi calculation, and bmi category (ex:Underweight). However, I am running into a few problems with my program.

Here's what I have so far:

from tkinter import* master = Tk() master.title("BMI Calculator") status = StringVar() Label(master, text="Name").grid(row=0, column=0) Label(master, text="Height (Inches)").grid(row=3, column=0) Label(master, text="Weight (Pounds)").grid(row=3, column=1) l1 = Label(master, textvariable=status).grid(row=9, column=0) name = Entry(master) h = Entry(master) w = Entry(master)

name.grid(row=2, column=0, padx=10, pady=10) h.grid(row=4, column=0, padx=10, pady=10) w.grid(row=4, column=1, padx=10, pady=10) Button(master, text='Calculate BMI', command= lambda: BMI(h, w).grid(row=8, column=1, sticky=W, pady=4)

def user_name(name): n = str(name.get()) status.set(n)

def BMI(h, w): inch_height = float(h.get()) weight = float(w.get()) meter_height = inch_height / 39.37 kilo_weight = weight * 0.453592 bmi = kilo_weight / (meter_height ** 2) return status.set(bmi) def BMI_interpretation(h, w): inch_height = float(h.get()) weight = float(w.get()) meter_height = inch_height / 39.37 kilo_weight = weight * 0.453592 bmi = kilo_weight / (meter_height ** 2) if bmi <= 18.5: status.set("Underweight") elif bmi > 18.5 and bmi <= 24.9: status.set("Normal") elif bmi > 24.9 and bmi <= 29.9: status.set("Overweight") else: status.set("Obese") master.mainloop()

However, Python is saying that my functions are invalid syntax (there is a red x symbol by def user_name(name), and when i remove the function completely, the red x moves to the next function). I am not sure why these functions are not working in my program. Also, I need the button in Tkinter to return all of values of the functions (name, BMI, and BMI category), not just the BMI(h, w) function.

Thanks!
